Click the Select
all button. From
the Source list, select
manual. From the Mode
list, select normal.

The X under Signal selection designates
that a signal has been tagged for data collection, and T designates
that the signal has been tagged as a trigger signal.

In the Duration field,
enter the number of sample points in a data buffer. Enter a Duration value
equal to the total number of sample points that you must collect for
a run. For example, if you have a sample rate of 1000 samples/second
and a stop time of 10 seconds, enter:

10000

Set the time axis for Simulink Scope blocks
equal to the sample interval (in seconds) times the number of points
in each data buffer. This setting displays one buffer of data across
the entire Simulink Scope plot.
